US Patent 11956258 Delayed replication for protection of replicated databases

Apparatuses and methods are disclosed for protection of data servers configured for data replication of a database. As an example, one apparatus includes at least one processing circuit configured to receive records indicating respective modifications performed on a first version of the database stored in a first data server of the plurality of data servers. The at least one processing circuit is configured to delay replication of the modification in one or more additional servers in the plurality of data servers for a respective length of time specified for the servers in security profile data. While delaying replication of the modification, the processing circuit determines a probability that the modification is malicious based on a first set of factors indicated in a security profile. If the probability is greater than a threshold specified in the security profile data, the processing circuit prevents the modification from being performed.
